But sometimes it is not enough, and the internal thermostat turns bright red. It’s heat stroke.

Under the effect of this hyperthermia, Heart rhythm disturbance And sharply, it also accelerates breathing and lung ventilation. Despite the increased internal temperature, the body conserves as much water as possible, stops sweating and the urine becomes dark or disappears for several hours.
